Histamine Care*

What is Histamine Care?

Histamine Care from EssentialSeries is a dietary supplement formulated for those who want to look after their daily routine around dietary histamine, especially in meals where this approach matters more.

The formula blends DAO, PureWay-C® vitamin C, and natural quercetin. Vitamin C contributes to the normal function of the immune system.

A clear formula: high-quality DAO, PureWay-C® vitamin C, and natural quercetin in delayed-release capsules.

DAO: the key ingredient in the formula

DAO is the star of Histamine Care. It’s a reference enzyme, and in this formula we’ve included it with very high activity: 36,288 HDU per capsule.

Plus, we’re not talking about any old DAO. We obtain it from pork kidney protein extract, a premium quality source, and it’s standardized to 7% in diamine oxidase. This allows working with a specific ingredient, with known quality and clearly defined activity.

HDU are units used to express the activity of DAO. In other words: it’s not just the milligrams that matter, the activity matters too.

PureWay-C®: premium vitamin C, not just any vitamin C

In Histamine Care we’ve included PureWay-C®, a vitamin C raw material developed by One Innovation Labs. Unlike conventional vitamin C, PureWay-C® combines ascorbic acid with lipid metabolites and citrus bioflavonoids, a technology designed to improve it.

PureWay-C® provides ascorbic acid, lipids from Oryza sativa, and citrus bioflavonoids from citrus fruit extracts. It’s a form of vitamin C with more work behind it, ideal for the development of our Histamine Care, a product based on quality and careful ingredient selection.

Natural quercetin for a more complete formula

We’ve completed the formula with quercetin, a natural flavonoid from the bud of Sophora japonica. We chose a 20:1 concentrated extract standardized to 95% quercetin to provide a high-quality ingredient with a transparent, natural composition.

Along with the DAO and PureWay-C®, quercetin helps round out the care formula, aimed at those seeking something more complete than DAO alone.

Convenient format to take with your meals

Histamine Care comes in delayed-release vegetable capsules. It’s a very practical format to integrate into your day, especially to accompany your main meals.

Just follow the usage directions on the package and adapt it to your routine. Simple and without preparations.

Who is this Care for?

Histamine Care fits especially for people who already know the concept and look for a DAO-specific formula.

Frequently asked questions

What difference does it make vs. a DAO formula from another brand?

The difference lies in the quality and declared activity of the DAO. Histamine Care provides DAO from pork kidney protein extract, standardized to 7% in DAO and with an activity of 8,640 HDU/mg.

Why do we include vitamin C?

Because vitamin C contributes to the normal function of the immune system. Also, in Histamine Care we use PureWay-C®, a premium raw material that combines ascorbic acid, lipids from Oryza sativa and citrus bioflavonoids.

What does quercetin add?

It adds value to the formula as a natural flavonoid of plant origin. We’ve used it from the bud of Sophora japonica in a concentrated and standardized extract.

Is it vegan?

No. Although the capsule is plant-based, the DAO comes from pork kidney protein extract, so the formula isn’t suitable for vegan or vegetarian diets.

When should you take it?

It’s designed to be integrated around meals. Follow the instructions on the package.
